Now that the NFL regular season has come to a close, I thought it would be a good time to take a look at the impact of each team's 2015 draft class. I ranked every team, from 1-32, based on the impact they received from their rookie draft picks. For the sake of this project, I focused solely on the rookies that were drafted. In other words, impactful rookie free agents weren't a factor in this ranking. Keep this in mind: This ranking is based solely on the immediate return of the picks. Many of the players selected suffered injuries or were stuck behind talented veterans on the depth chart. The ultimate winners of this draft won't be determined for at least a couple of years.
